Invisible Backlighting for Concealed Displays

精确、高分辨率、高精度的微孔钻孔,适用于隐形孔背光显示屏制造

先进的用户显示器正在突破新型汽车、飞机、机器人、电子产品、工业设备和消费产品的工程设计极限。如今,按钮或开关仅具有直观性和用户友好性是不够的。物联网和日益增强的连接性为产品用户提供了越来越多的数据,使得控制面板对于操作产品的客户来说变得混乱、分散注意力,而且往往很危险。

产品制造商需要能够不显眼地提供信息的显示屏,同时又不影响用户体验或设备的功能。理想情况下,不使用的显示元素在关闭状态下将变得不可见。

Our Micro-Hole Solution

Potomac 的研发团队通过为控制面板制造隐形孔背光,帮助制造出一种解决复杂产品展示问题的创新解决方案。这些新型显示器的元素在不需要时是肉眼看不见的。当需要时,来自后面的照明可以清楚地向操作员显示激光钻孔的微孔图案。

锥形微孔是用激光钻穿整个耐光材料的厚度。产品展示的典型观看距离决定了每个孔的大小。然而,由于成年人眼的分辨率极限在距离眼睛 1 米处约为 0.1 毫米,因此孔直径通常必须低于 50 微米,以便在关闭背光时完全看不到孔图案。

正是这些更大、更复杂的小孔图案,让眼睛在显示屏运行时能够看到显示屏。紧密的间距可在单位面积内产生更高的光强度,从而为观看者带来最明亮、最清晰、最锐利的图案。

Potomac’s Micro-Drilling Capabilities for Invisible Backlighting

Potomac’s R&D team has worked with our customers to fabricate new display technologies using the invisible hole backlighting technique. We can rapidly drill 1,000s of closely spaced holes measuring <20um in diameter with <50um spacing into metals, opaque plastics, or coated materials with the most optimized surface finishes and colors suitable for consumer displays. Most importantly, we can laser micromachine with the high precision, resolution and accuracy required to produce high light intensity that results in bright, sharp patterns for the product’s user. The ability to quickly and easily find a button or switch in many applications is critical to user safety.

通过优化和改进标准激光机床,我们开发了可重复、精确、高精度的微孔钻孔技术,使隐形孔背光装置得以实现。凭借对各种材料的丰富经验,我们专注于激光微加工薄、易碎且易损坏的材料,如玻璃和有机聚合物。隐形孔背光所需的精度对 Potomac 来说是天生的,因为我们在 30 年的历史中率先开发了许多激光微加工工艺。

当设计工程师寻找下一代显示器的新解决方案时,Potomac 在隐形孔背光应用方面的专业知识可以创造无与伦比的先进用户体验。


Also From the Goodfellow Group

Invisible hole backlighting requires light-resistant substrate materials — metals, opaque polymers, and coated films — with consistent optical density, surface finish, and thickness tolerances. Goodfellow supplies precision metal foils, opaque polymer sheets, and coated substrate materials suitable for high-resolution micro-hole array drilling.

Source display substrate materials — metal foils, opaque polymers, and coated films — from Goodfellow.

Coating uniformity, optical density consistency, and surface finish of display substrates can be characterized through Goodfellow’s ISO 17025-accredited materials testing lab using XPS surface analysis and EDX elemental mapping, supporting process development and material qualification for display applications.
